The perception is commonplace that e-business of all kinds, including e-commerce and e-government, is dependent on trust, and that trust can only arise if each party knows who the other parties are. This has resulted in a fascination with identification and identity authentication technologies. This, in turn, is seriously undermining privacy and ... trust.
The perception that identification in cybercpace is crucial if the potential of e-business is to be realised may be commonplace, but it is also seriously misguided. This presentation examines a collection of dangerous myths that pervade the immature e-business scene. It concludes with a series of propositions that offer a foundation for engendering trust in the conduct of transactions electronically.
The myths involve misunderstandings about the nature of identity, identification and authentication. They also involve the touchingly naive faith in cryptographic technologies to be able to reach out beyond the world of bits and overcome real-world complexities and messiness. Of yet greater concern is that the myths involve abject failure to appreciate the enormous impacts of these mistaken assumptions and misguided technologies on values that societies cherish, such as privacy of personal data and personal behaviour, and personal sovereignty.
So serious are the deficiencies that conventional public key infrastructures, and current proposals for biometric applications, need to be entirely abandoned and re-thought. To be effective, and to be publicly acceptable, the requirements, the architecture and the design must all reflect not only the needs of government agencies and corporations, but also those of other stakeholders, and especially of the public who are expected to fall in line with its dictates.
Demands by organisations for individuals' identifiers must be tempered, and limited to circumstances in which the need has been publicly justified. The existing notions of identification and identity authentication must be complemented by the concepts of value authentication and attribute authentication without identity, persistent anonymity, protected psuedonymity, and nyms.
The presentation builds on a substantial base of prior work. Access is provided to those documents in an accompanying annotated bibliography.
